An untyped pointer to driver-defined context information that the framework passes to the driver's EvtUsbTargetPipeReadComplete callback function.

TransferLength [in]

The maximum length, in bytes, of data that can be received from the device.

Return value

None

Remarks

The WDF_USB_CONTINUOUS_READER_CONFIG_INIT function zeros the specified WDF_USB_CONTINUOUS_READER_CONFIG structure and sets the structure's Size member. It also sets the structure's EvtUsbTargetPipeReadComplete, EvtUsbTargetPipeReadCompleteContext, and TransferLength members to the specified values.

Note that WDF_USB_CONTINUOUS_READER_CONFIG_INIT does not set the structure's EvtUsbTargetPipeReadersFailed member.

After calling WDF_USB_CONTINUOUS_READER_CONFIG_INIT, the driver can optionally add a EvtUsbTargetPipeReadersFailed pointer to the WDF_USB_CONTINUOUS_READER_CONFIG structure.
